3.3.2
According to ITU recommendation I.430 a multiframe provides extra layer 1 capacity in
the TE-to-NT direction by using an extra channel between the TE and NT (Q-channel).
The Q bits are defined to be the bits in the F
In the NT-to-TE direction the S-channel bits are used for information transmission. One
S channel (S1) out of five possible S-channels can be accessed by the ISAC-SX TE.
In the NT-to-TE direction the S-channel bits are used for information transmission.
The S and Q channels are accessed via the µC interface or the IOM-2 MONITOR
channel, respectively, by reading/writing the SQR or SQX bits in the S/Q channel
registers (SQRRx, SQXRx).
